Witness recall across repeated interviews in a case of repeated abuse.

In this illustrative case study we examine the three forensic interviews of a girl who experienced repeated sexual abuse from ages 7 to 11. She disclosed the abuse after watching a serialized television show that contained a storyline similar to her own experience. This triggered an investigation that ended in successful prosecution of the offender. Because this case involved abuse that was repeated on a weekly basis for 4 years we thus investigated the degree to which the child\u27s narrative reflected specific episodes or generic accounts, and both the interviewer\u27s and child\u27s attempts to elicit and provide, respectively, specific details across the 3 interviews collected in a 1 month period. Across the 3 interviews, the child\u27s account was largely generic, yet on a number of occasions she provided details specific to individual incidents (episodic leads) that could have been probed further. As predicted: earlier interviews were characterized more by episodic than generic prompts and the reverse was true for the third interview; the child often responded using the same style of language (episodic or generic) as the interviewer; and open questions yielded narrative information. We discuss the importance of adopting children\u27s words to specify occurrences, and the potential benefits of permitting generic recall in investigative interviews on children\u27s ability to provide episodic leads. Despite the fact that the testimony was characterized by generic information about what usually happened, rather than specific episodic details about individual occurrences, this case resulted in successful prosecution

How children talk about events:Implications for eliciting and analyzing eyewitness reports

Legal and social service professionals often question whether various features of young witnesses’ responses during interviews are characteristic of children’s event reports or whether these features are concerning findings that reflect degraded memory, outside influence, or other phenomena. To assist helping professionals and researchers who collect data through interviews, we aggregated findings from child eyewitness studies and revisited transcript sets to construct fifteen principles that capture how children talk about events. These principles address children’s earliest event narratives, how children report information as interviews unfold and typical features of their narratives, threats to the accuracy of answers, the influence of interviewers’ language on children’s styles of reporting, how testimonies compare across multiple interviews and multiple witnesses to the same event, and the structure of accurate and inaccurate reports. A summary table highlights the implications of these principles for interviewers and the decision-makers who analyze children’s reports

Psychometric properties of the Self‐assessment Practice Scale for professional training contexts: evidence from confirmatory factor analysis and Rasch analysis

Self‐assessment is a fundamental skill for professionals because self‐assessment can promote self‐regulated learning and professional development. However, studies reporting the use of self‐assessment instruments in the professional training context are scarce. This study aimed to re‐evaluate the psychometric properties of the Self‐assessment Practice Scale (SaPS), which was originally developed in the school context, and extend its use to the professional training context. A sample of 200 investigative interviewer trainees from Australia and North America were invited to complete the modified SaPS. After removing misfitting items, the confirmatory factor analysis results confirmed a first‐order four‐factor solution. The multidimensional Rasch analysis demonstrated that the resultant 16 items had satisfactory fit to the Rasch model. In general, the results supported the use of the 16‐item modified SaPS as a valid measure for the sample in this study. The potential of using the SaPS in professional training contexts is discussed

Design of Sports Compression Garments: Exploring the Relationship Between Pressure Distribution and Body Dimensions

In recent years, a wealth of research on the functionality of sports compression garments (SCGs) has emerged due to their increased popularity among athletes and SCG brands’ claims that they improve exercise performance, shorten recovery and prevent injuries. With most researchers from medical or sports science backgrounds, existing studies are biased towards these fields, neglecting considerations of users and the SCG-body-relationship. To address this gap, this study applied an online survey and wearer trials to create an understanding of user experiences with SCGs. 145 SCG users (65% male, 35% female) completed the online survey. Results show that the respondents have a positive attitude towards SCGs with 78% believing in their recovery-enhancing properties, whilst 49% believe that SCGs improve performance. To examine the behaviour of SCGs on the body, 33 wearer trials with active females (31.0 ± 8.57 years) were conducted. The participants’ body measurements were captured using a 3D body scanner (Size Stream, USA). Each participant was fitted into Skins A400 Women’s Active Long Tights and Long Sleeve Tops using the brand’s size chart. Pressures applied by the garments were measured at 22 locations using a pneumatic pressure measurement device (PicoPress®, Microlab, Italy). The wearer trials revealed that, despite high levels of user satisfaction identified by the online survey, compression levels varied widely across different individuals. This suggests a strong perceptual effect of SCGs. Variations in pressure levels are likely to be associated with variations in fit due to problems with the applied sizing system. The study adds a more garment- and user-focused outlook to the current research base and highlights the importance of adequate fit of SCGs. For SCGs to provide physiological benefits, they need to apply controlled pressure, which requires pressure prediction during the design phase. This will be addressed by the next stage of this research project

Pediatric supracondylar fractures of the distal humerus

Supracondylar fractures of the humerus are a common pediatric elbow injury that are historically associated with morbidity due to malunion, neurovascular complications, and compartment syndrome. True anteroposterior and lateral radiographs are essential not only for an accurate diagnosis, but also for creating a treatment plan for these injuries. A staging system (based on the lateral radiograph) for classifying the severity of the fracture helps guide definitive management. Nondisplaced fractures are treated initially with a posterior splint, followed by a long-arm casting. Closed reduction and percutaneous pinning is the preferred treatment for displaced or unstable fractures. If there is any question about fracture stability, patients should be seen within 5 days postoperatively for repeat radiographs to ensure that the reduction and pin fixation has been maintained. Understanding the anatomy, radiographic findings, management options, and complications associated with this fracture allow physicians to limit the morbidity associated with this relatively common pediatric injury

An Essential Difference between the Flavonoids MonoHER and Quercetin in Their Interplay with the Endogenous Antioxidant Network

Antioxidants can scavenge highly reactive radicals. As a result the antioxidants are converted into oxidation products that might cause damage to vital cellular components. To prevent this damage, the human body possesses an intricate network of antioxidants that pass over the reactivity from one antioxidant to another in a controlled way. The aim of the present study was to investigate how the semi-synthetic flavonoid 7-mono-O-(β-hydroxyethyl)-rutoside (monoHER), a potential protective agent against doxorubicin-induced cardiotoxicity, fits into this antioxidant network. This position was compared with that of the well-known flavonoid quercetin. The present study shows that the oxidation products of both monoHER and quercetin are reactive towards thiol groups of both GSH and proteins. However, in human blood plasma, oxidized quercetin easily reacts with protein thiols, whereas oxidized monoHER does not react with plasma protein thiols. Our results indicate that this can be explained by the presence of ascorbate in plasma; ascorbate is able to reduce oxidized monoHER to the parent compound monoHER before oxidized monoHER can react with thiols. This is a major difference with oxidized quercetin that preferentially reacts with thiols rather than ascorbate. The difference in selectivity between monoHER and quercetin originates from an intrinsic difference in the chemical nature of their oxidation products, which was corroborated by molecular quantum chemical calculations. These findings point towards an essential difference between structurally closely related flavonoids in their interplay with the endogenous antioxidant network. The advantage of monoHER is that it can safely channel the reactivity of radicals into the antioxidant network where the reactivity is completely neutralized

Low level methylmercury exposure affects neuropsychological function in adults

BACKGROUND: The neurotoxic effects of methylmercury (MeHg) have been demonstrated in both human and animal studies. Both adult and fetal brains are susceptible to the effects of MeHg toxicity. However, the specific effects of adult exposures have been less well-documented than those of children with prenatal exposures. This is largely because few studies of MeHg exposures in adults have used sensitive neurological endpoints. The present study reports on the results of neuropsychological testing and hair mercury concentrations in adults (>17 yrs) living in fishing communities of Baixada Cuiabana (Mato Grosso) in the Pantanal region of Brazil. METHODS: A cross-sectional study was conducted in six villages on the Cuiaba River. Participants included 129 men and women older than 17 years of age. They were randomly selected in proportion to the age range and number of inhabitants in each village. Questionnaire information was collected on demographic variables, including education, occupation, and residence history. Mercury exposure was determined by analysis of hair using flameless atomic absorption spectrophotometry. The neurocognitive screening battery included tests from the Wechsler Memory Scale and the Wechsler Adult Intelligence Scale, Concentrated Attention Test of the Toulouse-Pierron Factorial Battery, the Manual Ability Subtests of the Tests of Mechanical Ability, and the Profile of Mood States. RESULTS: Mercury exposures in this population were associated with fish consumption. The hair mercury concentration in the 129 subjects ranged from 0.56 to 13.6 μg/g; the mean concentration was 4.2 ± 2.4 micrograms/g and the median was 3.7 μg/g. Hair mercury levels were associated with detectable alterations in performance on tests of fine motor speed and dexterity, and concentration. Some aspects of verbal learning and memory were also disrupted by mercury exposure. The magnitude of the effects increased with hair mercury concentration, consistent with a dose-dependent effect. CONCLUSIONS: This study suggests that adults exposed to MeHg may be at risk for deficits in neurocognitive function. The functions disrupted in adults, namely attention, fine-motor function and verbal memory, are similar to some of those previously reported in children with prenatal exposures

Vitamin C supplement use may protect against gallstones: an observational study on a randomly selected population

<p>Abstract</p> <p>Background</p> <p>Animal experiments have shown a protective effect of vitamin C on the formation of gallstones. Few data in humans suggest an association between reduced vitamin C intake and increased prevalence of gallstone disease. The aim of this study was to assess the possible association of regular vitamin C supplementation with gallstone prevalence.</p> <p>Methods</p> <p>An observational, population-based study of 2129 subjects aged 18-65 years randomly selected from the general population in southern Germany was conducted. Abdominal ultrasound examination, completion of a standardized questionnaire, compilation of anthropometric data and blood tests were used. Data were collected in November and December 2002. Data analysis was conducted between December 2005 and January 2006.</p> <p>Results</p> <p>Prevalence of gallstones in the study population was 7.8% (167/2129). Subjects reporting vitamin C supplementation showed a prevalence of 4.7% (11/232), whereas in subjects not reporting regular vitamin C supplementation, the prevalence was 8.2% (156/1897). Female gender, hereditary predisposition, increasing age and body-mass index (BMI) were associated with increased prevalence of gallstones. Logistic regression with backward elimination adjusted for these factors showed reduced gallstone prevalence for vitamin C supplementation (odds ratio, OR 0.34; 95% confidence interval, CI 0.14 to 0.81; P = 0.01), increased physical activity (OR 0.62; 95% CI, 0.42 to 0.94; P = 0.02), and higher total cholesterol (OR 0.65; 95% CI, 0.52 to 0.79; P < 0.001).</p> <p>Conclusion</p> <p>Regular vitamin C supplementation and, to a lesser extent, increased physical activity and total cholesterol levels are associated with a reduced prevalence of gallstones. Regular vitamin C supplementation might exert a protective effect on the development of gallstones.</p
